An unusual case characterized by autoimmune hemolytic anemia, fever, polyarthralgias, was developed after PUVAtherapy. Investigation revealed ESR accelerated, complement consumption, diminished levels of C4 and C3, high levels of ANA were detected. In recent years, lupus erythematosus like syndrome was related with photosensitivity provoked by PUVA-therapy. Long-wave ultraviolet light was consider a precipitating factor in the development of autoimmune phenomena. On the contrary, in other researches suggests that PUVA induced alterations are not antigenic this discrepancy remains to be clarified. However this iatrogenic risk must be avoided with a clinical and serological controls.
一例以自身免疫性溶血性贫血、发热、多关节痛为特征的罕见病例在补骨脂素紫外线A(PUVA)治疗后出现。检查发现红细胞沉降率加快、补体消耗、C4和C3水平降低,检测到抗核抗体水平升高。近年来,类红斑狼疮综合征与PUVA治疗引起的光敏性有关。长波紫外线被认为是自身免疫现象发生的一个诱发因素。相反,其他研究表明PUVA诱导的改变不是抗原性的,这种差异仍有待澄清。然而,必须通过临床和血清学检查来避免这种医源性风险。
